Application filed August 8, 1928,

The present invention relates to apparatus for the spraying and atomizing of melted paraffin wax, other waxes and similar substances, particularly for the treatment of the human body.

It has also been found that the known spraying apparatus are unsuitable for this purpose, principally owing to the velocity of discharge of the fluid wax under pressure, such as air pressure, when the wax and pressure fluid are allowed to discharge with freedom, which results in the formation and dispersion of a line vapor or nebula, to the great annoyance and discomfort of operator and patient.

In order to avoid this, according to the invention the fluid parafiin or the like is atomized by forcing it out of its container under pressure preferably by means'of compressed air through a nozzle provided with a rim having sharp edges, after a rotary or whirling motion has been communicated to the said paraffin or the like immediately in front of the nozzle opening by means of fine channels arranged at an inclination to the direction of emergence. It has been found that, with such an arrangement of the nozzle, even with the finest atomizin of the parafiin or the like the formation 0 vapour is avoided either entirely or, at least, to such 'an extent that no discomfort to the patient or the doctor or the person under treatment, as the case may be, can occur.

ln order to render the apparatus particularly suitable for the treatment of the human body, it is provided on the one hand with an eyelet for hangin it up on a suitablesupporting member gsuch as a pull member or the like.) adapted to allow of its unhindered manipulation, and it is further provided with a handle arranged opposite to the nozzle p and with a second handle arranged on the periphery of the container in proximity to the end of the nozzle and serving for the guidance of the apparatus with the second hand. The compressed air is introduced into the container through the first named handle which is hollow and is connected with a cover serving to close the container, in which latter a separate filling hole having a closure is also regard to the bore are cut Serial No. 298,837, and in Germany April 7, 1927.

provided. valve, which stem is provided with a handle, is also guided in the said first named handle.

A preferred constructional form according to the invention is illustrated b way of example in the accompanying rawings, in which:

Fig. 1 shows an apparatus constructed according to the invention in longitudinal section, and

Fig. 2 shows a section through the nozzle body on a larger scale.

The apparatus consists of a container 1, which is generally cylindrical and is provided with a cylindrical neck 3 which is narrowed in cross section by the provision of a bottom portion 2 having a truncated conical The said neck 3 is provided with a at one part by the surface. bore whlch 1s narrowed provision of an internal circular flange 4.

The nozzle bushing 5 is held by means of a The stem of the nozzle closing 1 circular flange 6 in position within said bore between the flange 4c of the container neck 3 and a screwed nozzle ring 7 which is screwed into the bore of the container neck. The nozzle bushing 5 is provided with a bore which is narrowed in the middle and widened towards the ends and which is closed or opened by the conical point of a needle valve 8 according to the position of the latter. The forward end of the valve is guided in a screwed member 9, which is screwed into the widened part 10 of the bore of the nozzle bushing. The widened bore 10 is connected behind the screwed member 9 with the interior of the container by means of holes 11 formed in the wall of the nozzle bushing.

In the stepped and widened mouth of the bore of the nozzle bushing 5 a retarder and concentrator is inserted, which comprises a in 12 provided with a head 13 adapted to obstruct the bore. Channels 14 running in screw form or in an inclined direction with in the cylindrical outer surface of the head 13. The pin 12 is held in' position in the bore of the nozzle bushing by means of a nozzle tip 15 which is screwed into the mouth of the bore and is provided with a screwed flange closely surrounding the head 13. In advance of the front surface of the head 13 a nozzle outlet pas- - sage 16 is formed in the ti 15,-through which passage the paraflin issulng from the guide channels 14 is discharged. The nozzle passage 16, as shown, is of smaller diameter than the head 13 and thence flares gradually to a larger diameter than the head 12 at its outer end, where it is furnished with a sharp edged rim 16 providing for the off-flow of the atomized wax without allowing the wax to congeal and form an interfering crust deposit on the margin of the nozzle tip.

The container 1 is closed at the end 17 opposite to the nozzle by means of a screw cover 17 to which a ring shaped hollow handle 18 is connected. On the handle l8 a connection flange 1-9 havin a connection piece, nipple or fitting 20 for a exible pipe is provided. The handle 18 is also provided with a second connection flange 21 furnished with a safety valve 22. The rear end of the needle valve 8 passes through a stuffing box 23 arranged in the cover 17' and is also guided at its outer end in the handle 18. Qn the needle valve 8 within the handle ring 18 a hand piece 24 is arranged,'by means of which the needle valve can be opened against the pressure of a closing spring 25.

On the periphery of the container 1 in proximity to the nozzle end a second handle 26 for manipulating the apparatus with the second hand is arranged and in addition to this eyelet 27 is provided on the periphery of the-container at the end where the handle 18 is located, for the purpose of enabling the apparatus to be hung up on a suitable supporting member, such as a holder or pendant.

The cylindrical neck 3 of the container, which encloses the nozzle, is surrounded by an electrical heating element 28 in order to ensure that the paraflin does not cool down before its emergence and remains sufliciently liquid. The heating element is connected by means of a lead 29 with a plug contact 30 arranged at the upper end of the container.

consequence of the air pressure acting on its surface the parafiin passes through the holes 11 into the bore of the nozzle and is pressed through the guide channels 14, whereby a whirling motion arises inthe nozzle outlet passage, which motion continues to show itself in the parafiin issuing from the nozzle in an atomized state. In this way very fine atomization is obtained, without excessively high atomization speed, which latter is the cause of the formation of free vapour.

What I claim is:

1. In an apparatus for liquefying and spraying liquid paraflin wax and the like, a receptacle for holding a body of wax, said receptacle having an outlet, means for heating the receptacle to liquefy the wax, means for introducing a compressed fluid intol the receptacle to place the body of wax under pressure therefrom, a discharge nozzle at the outlet end of the receptacle having inlet and outlet ends, the former immersed in the body of liquefied p'aralfin and having lateral inlets for the entrance of the parafiin thereto, and

a retarder in the nozzle between the inlet and outlet ends thereof having peripheral spiral channels for imparting a whirling motion to the discharging paraffin liquid.

2. An apparatus for liquefying an atomizing paraflin wax and the like, comprising a receptacle for holding a body of wax and having an outlet at one end and a filling in let at its opposite end, a closure for the filling inlet, a ring-shaped handle carried 'by said closure and provided with a fluid passage communicating with the receptacle, means connected with said passage for admittin a fluid under pressure to the receptacle, a ischarge nozzle at the outlet end of the receptacle, a valve controlling said nozzle and having a portion disposed in the opening of the ring-shaped handle, and a manipulating element on said valve in said opening whereby the hand of the operator engaging the ringshaped handle may manipulate the valve.
